Autoradiography of detached parts of shoots at grain-filling stage 36 h after supplementation with tracer. After the PETIS experiment and the sufficient decay of107Cd within the test plants, autoradiography was carried out to obtain the static109Cd distribution in detached parts. (a) Photograph of test plants. (b) Autoradiograph of test plants. The same views are shown in (a) and (b). The pair of circled numbers indicates the nodal portions where the leaf was cut.
